Perturbation theory in the invariant subspace
Abstract
The unitary transformation of pathintegral differential measure is described. The main properties of perturbation theory in the phase space of actionangle, energytime variables are investigated. The measure in cylindrical coordinates is derived also. The dependence of perturbation theory contributions from global (topological) properties of corresponding phase spaces is shown.
